RANSOM Y. BOVEE, OF DENVER, COLORADO, ASSIGNOR OF ONE-FOURTH TO WILLIAMM. HARDISON AND ONE-FOURTH TO JOHN S. SETTLE, JR., OF DENVER, COLORADO.

WRENCH.

To all whom it may concern:

Be it known that I, RANsoM Y. BOVEE, a citizen of Denver, Colorado,residing at No. 772 South Grant avenue, in the city and county of Denverand State of Colorado, have invented certain new and useful Improvementsin Wrenches, of which the following is a specification.

This invention relates to improvements in wrenches, and particularly thetype of adjustable-j aw wrenches in which the relation of the handle tothe jaws is variable, to the end that the wrench may be used in themanipulation of nuts which would be inaccessible to the ordinary wrenchin which the relation of the handle to the aws is fixed.

More specifically my invention consists in an improved connection andcontrolling device between the handle and the aws.

Exactly. what constitutes the invention will be fully described in thefollowing specification, and succinctly defined in the appended claims.

In the accompanying drawings, which are to be taken as a part of thisspecification, and in which I have shown a merely preferred form ofembodiment of the device, Figure 1 is an elevation of a wrenchexemplifying the invention; Fig. 2 is a sectional view on the lines 22of Fig. 1 and Fig. 3 is a detail per- I spective of the ratchet disk.

Referring to the numerals on the drawings, 1 indicates in a general waythe solid frame of a wrench, comprising an oblong j aw-carrying member 2and a circular member 3. Mounted to slide longitudinally of saidaw-carrying member is a pair of movable jaws, the said jaws, for thesake of rigidity in o eration, preferably substantially surrounc ingsaid member 2. The said jaw-carrying member is preferably grooved orrecessed at one side to accommodate a jaw adjusting screw 4, which is opositely threadedas indicated at 5 and 6 on t 1e opposite sidesrespectively of 'a medially disposed thumb-nut, which, taking into acavity 7 in the member 2 transverse to the screw 4 holds the latteragainst transversemovement rela tive to the member 2, while permittingfree rotation thereof. The jaws, being shaped to correspond tothe'transverse contour of the member 2 are made to closely embrace thesame as aforesaid, and are respectively provided with opposite screwthreads to corre- Specification of Letters Patent.

spond to the opposite threading of the two ends of the adjusting screw4.

Pivotally attached to the member 3 of the frame is a handle 8. Thelatter is preferably bifurcated, having legs 9 and 10 adapted tostraddle the member 3, and to be pivotally connected therewith as bymeans of a pin 11 extending through apertures in the ends of said legsand a corresponding aperture in the member 3. The said member 3, on itscircular periphery, is provided with a series of notches 12, with whichis adapted to cooperate means next described for holding the handle andframe in locked relations, for

permitting relative pivotal movement there- I of, and for determiningthe direction in which such movement may be made. The said meanscomprises preferably a disk 14 apertured as at 15, so that it may berotatably held upon a pin 16 which is securely held in the handle 8between the bifurcations thereof, so that the disk may project beyondthe outer surface of each leg of the handle, in order that it may bemani ulated.

The disk is so relative y mounted with respect to the circular member 3that the circular periphery of the disk will engage the notches 12 ofthe member 3, as clearly shown in Fig. 1. For the attainment of theobjects heretofore stated, the said disk 14 is provided with a series ofradial recesses 17, on one flat face, extending from points adjacent thecenter and with their bottom walls inclining downwardly towards thecircumference, and a series of similar radial recesses 18 on the otherflat face, with their bottom walls inclining oppositely from theinclination of the bottom walls of recesses 17. The recesses 17 and 18are alternately arranged around the peripheral edge of disk 14, with aseparating spur 19 between each two adjacent recesses.

Secured to the handle 8 is a suitable means for yieldingly maintainingthe disk 14 in any position to which it may be rotated, said meanspreferably comprising a spring 20 rigidly secured to the handle at oneend and having a bow or hump adjacent the other end adapted to springinto the recesses 17 and 18. In operation, the aws being adjusted to anut by manipulation of the thumb screw, if it is desired to maintain thehandle in any fixed relation to the wrench frame, the disk 14 ismanipulated by means of a milling on the circular periphery until one ofthe spur portions 19 is in engagement with one of the notches 12 of themember 3. In this relation there can be no relative movement between thehandle and the wrench frame. If it be desired to ermit a ratchetmovement of the handle relatively to the Wrench frame in one directionor the other, it is only necessary to turn the disk 14 until a recessedportion 17 or 18 shall be engaged with a notch 12 of the member 3,whereupon ratchet movement of the handle may, be accomplished in onedirection or the other, according to the direction of inclination of therecess with which the notch 12 of the member 3 is engaged, the partsbeing locked against relative movement in the opposite direction by theengagement of the outside face of the bottom wall of the said recesswith the wall of the straight notch 12 in the member 3, as Will bereadily understood.

The particular advantage of my invention lies in the use of the disk 14having the peculiar recesses and spurs, whereby the relative movementbetween the handle and wrench frame may be permitted, prevented, or itsdirection controlled, by simply giving the disk a partial rotation.

To one skilled in the art further descrip tion of the advantages andmode of operation appears to be superfluous and it is therefore omitted.

What I claim is 1. In combination, a wrench frame havin a circularportion provided with periphera notches, a handle pivoted to saidcircular member, and a disk mounted in said handle and adapted to permitor prevent relative pivotal movement between said handle and circularmember as desired, and to determine the direction of pivotal movement,if any by engagement with the peripheral notches aforesaid, havingalternately arranged radial recesses, provided with oppositely inclinedbottom walls respectively, and a spur portion between the alternaterecesses.

2. In combination, a wrench frame, havin a circular portion providedwith peripheral notches, a handle pivoted to said circular portion, anda disk mounted in said handle havin alternately arranged radialrecesses, provided with oppositely inclined bottom walls respectively, aspur portion between the alternate recesses, and a series of notches;and a spring mounted on said handle and provided with a hump adapted toengage one of said last named notches.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
